Description
1.2343 is one of the Hot Work, Chromium type tool steels. It is relatively low in carbon content and has good toughness and deep hardens by air quench from heat treatment. Good combination of toughness, hardness and wear resistance in hot. Resistance to softening and to cracking.
Applications
H11 is often used for highly stressed structural parts such as aircraft landing gear. It resists softening at temperatures up to 537℃ while retaining good ductility . Tools for hot forging of light metal. Pressure die casting tools. Dies, mandrels, punchers, knives, mould.
